The most complete enantiornithine from North America and a phylogenetic analysis of the Avisauridae

A 75 million year old bird skeleton from a threatened national monument in Utah represents the most complete skeleton ever found in North America for a long extinct group of birds called enantiornithines. This large, fossilized bird provides important new insight into the evolution of flight. It has several advanced adaptations for flying, which show that the Enantiornithes evolved these features separately from living birds.
